DEVICE FOR FORMING ANNULAR SHEET lVlETAL RINGS.

SPECIFICATION forming part of Letters Patent N 0. 595,287, datedDecember 14, 1897.

Application filed April 27, 1897- Serial llo. 634,079. (No model.)

To aZZ whom it may concern.-

Be it known that 1, JOHN A. CARLSTEDT, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in Attachments orDevicesfor Forming Annular Sheet-Metal Rings; and I do hereby declare thefollowing to be a full,

clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to letters of reference marked thereon, which form a part of thisspecification.

This invention relates more particularly to a novel construction ofapparatus or device for forming circular metal rings from a continuouspiece of flat and straight sheet metal, said apparatus being intendedfor use in connection with that class of machines known asbeading-machines.

The present invention has for its primary object to provide an apparatusor device of the nature hereinafter specified, working in conjunctionwith the beading-rolls of a head in g-inachine, wherebyastraight andflat piece of sheet metal which is fed between said rolls is suitablyornamented and beaded and at the same time is forced into the shape of aflat annular ring.

Heretofore flat rings of sheet metal were cut in short pieces by meansof a hand-shears, being suitably curved, and such pieces, usually four,five, or six of them, were then placed end to end and soldered togetherto form the completed fiat annular ring, or such pieces had to be forcedfrom the blank of sheet metal by means of suitable dies and thensoldered end to end, as stated. This method of producing fiat rings ofcomparatively large diameter, was slow and tedious, as well asexpensive.

A further object of this invention, therefore, is to obviate theseobjections and provide a band or ring having a better and more finishedappearance.

With these several objects in view the invention consists in the novelconstruction of attachment or device for forming annular rings of sheetmetal, as well as in the novel arrangement and combination of same withthe rolls of a beading-machine.

The invention consists, furthermore, in the details of construction andthe peculiar combinations of the parts of the apparatus or deviceforming my invention, all of which will be hereinafter fully described,and finally embodied in the clauses of the claim.

The invention is clearly illustrated in the accompanying drawings, inwhich- Figure 1 is a perspective view of a heading machine, illustratingin connection with the same my novel form of ring-forming device orapparatus embodying the principles of my invention. Fig. 2 is a top orplan view of the apparatus or device. Fig. 3 is an end view of the samewhen looking in the direction of arrow at in Fig. 2; and Fig. at is across-section, taken on line y y in said Fig. 2, when looking in thedirection of arrow 2 Fig. 5 is a bottom view of the ring-forming deviceor attachment, and Fig. 0 is a detail view illustrating a cross-sectionof the lower beadroll axle and that portion of the framework of thebeading-n1achine and one means of securing the ring-forming device orattachment in its operative position on said portion of the framework ofthe beading-machine.

Similar letters of reference are employed in all of the above-dcscribedviews to indicate corresponding parts.

In the accompanying'drawin gs, A indicates the general construction of abeading-machine comprising the usual frame portions a and a andoperating mechanism a for operating the j o urnals b and I), which arerespectively provided with the feed-rolls b and if, as clearlyillustrated in Fig. 1. My novel construction of device or apparatus forforming a flat strip of sheet metal into a circular shape as it passesbetween said rolls 7/ and b consists, essentially, of a flat plate 0,forming a table, and has an opening 0 through which the contactingsurfaces of the rolls and b project for properly forcing the sheet-metalband cl over the upper surface of the table 0 when the machine is inoperation. lhe under side of said table 0 may be provided withsuitablyarranged strengthening-ribs c and a pair of clamping-leaves 0having the curved surfaces c", adapted to be fitted around and en1-brace the frame portion a of the beadingmachine A and clamped in itsoperative position by means of a bolt 6 and nut e passing through theperforated ears or lugs c on said clamping-leaves 0 all of which isclearly illustrated in Fig. 6 of the drawings.

Secured upon the upper face ofthe table 0, by means of screws f passingthrough aperforated flange f, or in any other well-known manner, is aguidef, having the u pwardly-extending guiding edgesf extending backcontiguous to the edge a of the opening a in the plate or table 0 andterminating in a suitablyconstructed bearing portion f as clearly shownin Figs. 2, 3, and 6. Said guide is also provided with an extra guidinglip or flange f projecting at a right angle from said edges f said lipor flange being approximately parallel to the uppersurface of saidtable, whereby a strip of sheet metal can be laid on its flat side onsaid table and passed beneath said lip or flange f, as clearlyillustrated in Fig. 1.

When a wide strip or band of sheet metal is to be formed into an annularflat ring, a second guide 7L may be employed, said guide having the 3-shaped guiding portion h and being adj ust-ably secured by means ofscrews or bolts 7L2 and nuts 71/3 in a pair of slots 0 in the plate ortable 0, as clearly represented in Figs. 1, 2, 4, and 5. Thus it will beevident that said guide h may be adjusted so that its guiding portion 71will readily grip the edge of the sheet metal,and said metal thuspassing between the two guidesfand h is prevented from buckling, as willbe understood.

As will be more especially seen from an inspection of Figs. 2 and 3, thesaid table or plate 0 is provided with a suitable scale or index, as 0and adjustably arranged above said plate 0, by means of screws or boltsg and g passing through suitable slots 0 and c in the table or plate 0,is a plate i, and secured in like manner to the under surface of saidtable or plate 0 is a second plate j. The plate i is slightly raised inthe middle and has secured thereto in any well-known manner a pair ofguide-plates t" and i connected means of a U shaped guiding-surface 2'against which the edge of the sheetmetal strip or band d is passed as itis fed from the rolls b and 11 between said guide-plates t" and 4?. Atone end of said plate 1' is an upright or post arranged in a bearingportion f' of the guide f, whereby when the bolts or screws 9 and g areslightly loosened the plates 2' and j, as well as the guide-plates i andt connected with the plate 11, can be moved laterally by means of asuitable rod and handle i and a pointer t on a projection or othersuitable part of the guide-plate 2' set at any desired point on thescale o As an extra precaution to prevent the metal from buckling asecond plate 70, having a U-- sha ed guiding ortion k,ma be em 10 ed P Py P y 1 said plate having a perforated projection and a screw or bolt 70and nut 70, passing through a slot 6 in the plate or table 0,

whereby said guide 70 can be adjusted and secured at the proper angle onthe upper surface of the. table 0, as will be clearly understood.

To prevent the end of the strip or band of metal from passing downthrough the opening 0 in the table or plate 0, the guide-plate t" isprovided with a lip or projection, as i which extends over said opening,as shown in Figs. 2 and 5, and to a position in close proximity to thecontacting surfaces of the two rolls (2 and h The operation ofthehereinabove-described device or apparatus is very simple and will bereadily understood, being perfectly operative for the purposes set forthof making from a continuous flat strip or band of sheet metal flatannular rings of different sizes and widths.

It will be understood that changes may be made in the arrangements andcombinations of the several parts, as well as in the details ofconstruction thereof, without departing from the scope of my presentinvention.
